Book VII - Chapter XXIV - How King Arthur pardoned them, and demanded of them where Sir Gareth was.
THEN goodly they said all at once, God forgive you, and we do, and pray you that ye will tell us where we may find Sir Beaumains. Fair lords, said Sir Ironside, I cannot tell you, for it is full hard to find him; for such young knights as he is one, when they be in their adventures be never abiding in no place. But to say the worship that the Red Knight of the Red Launds, and Sir Persant and his brother said of Beaumains, it was marvel to hear. Well, my fair lords, said King Arthur, wit you well I shall do you honour for the love of Sir Beaumains, and as soon as ever I meet with him I shall make you all upon one day knights of the Table Round. And as to thee, Sir Persant of Inde, thou hast been ever called a full noble knight, and so have ever been thy three brethren called. But I marvel, said the king, that I hear not of the Black Knight your brother, he was a full noble knight. Sir, said Pertolepe, the Green Knight, Sir Beaumains slew him in a recounter with his spear, his name was Sir Percard. That was great pity, said the king, and so said many knights. For these four brethren were full well known in the court of King Arthur for noble knights, for long time they had holden war against the knights of the Round Table. Then said Pertolepe, the Green Knight, to the king: At a passage of the water of Mortaise there encountered Sir Beaumains with two brethren that ever for the most part kept that passage, and they were two deadly knights, and there he slew the eldest brother in the water, and smote him upon the head such a buffet that he fell down in the water, and there he was drowned, and his name was Sir Gherard le Breusse; and after he slew the other brother upon the land, his name was Sir Arnold le Breusse.
